Regarding big models, what are the big companies doing recently? The latest news is: AI programming tools .

After all, it is so popular that an 8-year-old girl uses it to learn AI, and the "performance" of building a chat robot in 45 minutes has been watched online by 1.8 million people.

Due to the large number of onlookers, the young man later opened a class on the spot, and thousands of people signed up for his Cursor course.

Actually, Cursor was originally a branch of Microsoft's open source code editor VS Code .

It provides multiple AI models, including GPT-4, GPT-4o, and Claude 3.5 Sonnet, and you can generate code by chatting with the large model.

In addition, AI chat is also suitable for code review and completion.

Query information in the code repository or reference specific files directly through the chat interface without switching to other websites or search engines.

In addition to supporting a wide range of models, Cursor also has many commendable aspects in product design.

For example, the new “cursor position prediction” feature was launched in May this year .

After modifying a code, AI automatically predicts the next place you want to modify, eliminating manual navigation.

Another example is the multi-line editing function, where AI suggests modifying multiple lines of code at once, saving more time and is often used for formatting adjustments.

By combining the two, you can easily adjust all the formats at once:

When you modify the format of a line of code, you only need to press the tab key a few times and the format of the entire file will be adjusted.

These designs are also the main difference between Cursor and competitors (such as GitHub Copilot) .

Lianchuang Sanger said that Cursor mainly focuses on the functions after automatic completion, that is, finding and fixing errors, and answering code bases.

When people think of AI+coding, they first think of AI-driven automatic coding. In this regard, tools such as GitHub Copilot have done a good job.

He also wrote a blog post about tips for fast code editing.

In addition to the gameplay mentioned at the beginning, other netizens have also used Cursor to build their own productivity tools.

In 3 weeks, 11,000 lines of code were used to build a video editor that is compatible with both web and mobile devices.

It’s not a dream to create a Figma plugin in just a few minutes.

By the way, there is another figure that cannot be ignored among these gameplays - Claude 3.5 Sonnet.

Although OpenAI is the financial backer of Cursor, Cursor will now quietly switch the default model to Claude (doge) when a new user calls up code completion for the first time.

The reason is that it works well.

OpenAI bets on $400 million valuation

At present, Cursor's traffic has surpassed GitHub Copilot, the pioneer in the AI ​​code editor industry.

Even though the subscription fee is twice as expensive.

You should know that Cursor was not officially released until January 2023, while GitHub Copilot was released in June 2021 and the subscription version was launched in June 2022.

Just recently, Anysphere, the company behind Cursor, completed a new round of financing of US$60 million (approximately RMB 430 million) , led by a16z, with participation from Thrive Capital, OpenAI Startup Fund, Google Chief Scientist Jeff Dean, and OpenAI Research Scientist Noam Brown.

The founders of Stripe, GitHub, Ramp, Perplexity, and OpenAI are also among the investors.

After this round of financing, Anysphere’s valuation reached US$400 million (approximately RMB 2.85 billion) .

Forbes quoted people familiar with the matter as saying that the company's annual recurring revenue has exceeded US$10 million (approximately RMB 71.24 million) .

The official blog shows that Cursor has more than 30,000 users, including some of the world's largest companies, famous research laboratories and start-ups.

There are four founders of Anysphere: Aman Sanger, Sualeh Asif, Michael Truell and Arvid Lunnemark.

All four graduated from MIT.

According to Aman Sanger, he and Michael Truell were high school classmates and later went to MIT together. Cursor was born out of a short attempt after they graduated:

They are all avid users of GitHub Copilot, and based on this love, they began to try to apply Transformer to CAD software in June 2022.

Due to limitations in data and model capabilities, this attempt was not successful. It was not until December 2022 that they gained early access to GPT-4 and discovered that GPT-4 could completely change the experience of AI programming, which prompted them to pick up the idea and start building Cursor.

In August 2023, the Cursor team consisted of only five people. Even today, the team remains small: 12 engineers and researchers.

Finally, let me share a piece of gossip: a project comparable to Cursor has been launched in China.
